PCI-6220 Analog output to Biometrics DataLOG?

Hello all,
I am trying to send an analog signal to our Biometrics DataLOG device. Currently, I have the PCI-6220 card installed and am running the signals through a BNC-2111 DAQ. I am getting no output from our card through our DAQ, any suggestions? Thank you!

Provide some detailed information. How is the 6220 configured? How is it wired to the bnc? Do you see an output when you test the device in MAX? Are you checking the output with a meter or a scope or are you just relying on this unknown (to most of us) logger?

PCI-4451 Analog Output using FIFO allocation mode

I'm using a PCI-4451 DSA device to generate a short length (<50 updates) repeating pulse train. I want to write directly to the 4451's onboard FIFO so that I only have to transfer data to the device once and let the 4451 continuously regenerate the pulse train on its own. Using the the AOCONFIG.vi I set the allocation mode to "6" (use FIFO Memory). But when I write to the buffer, and then call AOSTART.vi, I get no output. Sometimes my system simply crashes. In either case, I get no LabVIEW generated errors when I set the allocation mode to "use FIFO memory." According to my 4451 documentation, I do have an AO FIFO, so it should be working. What could be going wrong?

Thanks for your response,
I used the VI you linked to and the non-FIFO mode AO works fine. In FIFO mode, it does end up generating an output, but it only iterates through the buffer once, no matter what the input to "number of buffer iterations" is on AOSTART.vi. I want it to regenerate indefinitely, but wiring "0" to "number of buffer iterations" and allowing regeneration on AOWRITE.vi doesn't make it do that. Could this be caused by a driver problem?
Also, I figured out that if I run a non-FIFO mode AO, stop the VI (I allow AOCLEAR.vi to execute), and then switch to a FIFO mode AO without first shutting down LabVIEW, my system locks up. It's not enough to just close the VI and reopen it to get FIFO mode to run again without locking up; I
actually have to exit and restart LabVIEW. Running a FIFO mode AO first and then runnning a non-FIFO mode AO causes no problems. I'm using Win2k professional and LabVIEW 7.

Read Data (ASCII) and send to analog output

Hello
I have the following MAX configuration:
Analog input task, continous, 2 samples, rate 100Hz (PCI-6024E)
Analog output task, continous, 64 samples, rate 100Hz (PCI-6723)
The cards are synchronized by the RTSI bus.
With Dasylab I display signals from load cells by the input task. A "Read Data" module sends values to the output task. The "Read Data" module has the following settings: Output in realtime, synchronisation with analog input task, file is an ASCII, block size 4 values, no ascii time channel.
Additional settings for DAQmx are done by DasyLab:
Analog input: Driver buffer 30
Analog output: Driver buffer 30, output start after 2
When I start DasyLab I get a DAQmx failure (after a couple hours): DAQmxReadAnalogF64, Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten.
Could anyone please explain, how to configure analog input/output task and the DasyLab settings (Read Data)? - Attached the DasyLab diagram.
Additional information: The application should read and display signals from a test bench (load cells). The output shall feed external controllers. The input and output signals shall be displayed on the same chart (as realtime as possible).
Thank you
Regards Samuel

Thanks for the prompt reply! - I have changed the settings to the following:
Analog input task, continous, 16 samples, rate 100Hz, driver buffer 32
Analog output task, continous, 16 samples, rate 100Hz, driver buffer 32, output start after 32
In the "Data read" module the block size is now 16 at 100Hz
With this setting, DasyLab runs, but only for around 12 hours.
The following error occurs:
"Read date module name" / The data flow is blocked by one of the following modules.
Followed by:
Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten.
Is there something else I have to care? Could it be problematic to send signals from different modules to the same Chart Recorder module? I use DasyLab version 11.

How do I configure 128 channels of DIO and 128 channels of Analog output with the availability of 3 pci slots

I have only 3 slots of PCI or 4 slots of ISA bus, I want to configure with the minimum possible modules to attain 128 channels of DIO and 128 channels of analog output. This is inturn fed to the PCM (Pulse code Modulator). The cards will be placed in industrial PC.

Associate Engineer-Marketing,
Using just those 3 PCI slots you're not going to be able to get the 128 analog output channels. You will probably want to go either the MXI-3 (PCI bus extender) to a PXI chassis or E Series DAQ card to a SCXI chassis for such a high channel count system. Which analog output cards and which digital I/O cards you will want depends on your application. You will have to decide whether you will need static or dynamic analog output as well as whether you need clocked digital I/O or not. I highly recommend contacting our internal sales department at 1-800-433-3488. They are great at helping specify systems.

The device PCI 6036E: Analog Input error:"the device is not responding to the base address",Output :No signal

I am using PCI 6036E DAQ card, DAQ 6.9.2. , I have not connected to any external device.
When I tested card(in Test Panel of MAX2.2,DAQ 6.9.2) an error appearing �the device is not responding to the base address� � then I pressed Yes, Then TestPanel window appearing�
In analog Input Tag, there is an error �-10805�. This error also appearing when I run the standard analog input samples (use Delphi 6.0).
I tested analog output functions in TestPanel, Delphi Examples, LabView 6.1. There are not error appearing but there is not output signal (using Oscilloscope to see).
Output, Input digital functions are working correctly.
Next I try to foll
ow all the instruntions as recommended:
-Changing TO another slots PCI
-Reinstall Os WinXP,98SE�
-Use another Computer�
But all of the cases are still not working.(the above error still appeared, no output signal)

Nvd,
I'm sorry to hear about the problems that you are running into with your DAQCard. I can understand your frustration with the errors that you are seeing. You mention that you have tried to do some troubleshooting, I was wondering if you have tried all the troubleshooting techniques listed in this KnowledgeBase:
http://digital.ni.com/public.nsf/websearch/DCFCDB240788F8D486256D6A00834D80?OpenDocument
If you have tried all of those things, I would suggest one additional thing to try. I would suggest updating your NI-DAQ drivers to version 7.0. These drivers are the newest versions of our Data Acquisition Drivers, and can be downloaded from our website here:
http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C128D?OpenDocument&

PCI Card for Analog output in the range of 10mv

dear ni,
                I want to know about the PCI card that can be generate analog output in the range of maximum 10mv. i am going to use for caliberation of loadcell, strain gauges devices.
could you tell me on which PCI card will support this type of application.
Regards,
Balaji DP

Try: http://www.ni.com/dataacquisition/
These have analog output voltages < 10V:   http://sine.ni.com/nifn/cds/view/main/p/sn/n12:7604,n3:7853/lang/en/nid/1036/ap/daq
You need something with a high bit count to get good resolution at 10 mV, such as the PCI-6010 which has a 16 bit D/A.
Here are the minimum voltage specs for the 6010:
Minimum Voltage Range
-0.2..0.2 V
      Range Accuracy
283 µV
      Range Sensitivity
6.4 µV

High Noise on Analog Output PCI 6289

Hi guys
I am using a PCI 6289 M series device for A/D characterization , I am using the device both for the analog output generation and also for data acquistion of the digital lines , The dynamic tests for the A/D were showing a very poor SNR ratio of the ADC, it is a 12 bit adc so technically in the ideal case i should atleast see 90 db but the resulting figure was way lower around 40 db .
I connected the A0 from the PCI 6289 brought out to a scb-68 block to a RHODE and SCHWARZ spectrum analyzer , the above spectrum analyzer is a decent one with good analysis capability and I was surprised to see a SNR of 50 db , the data sheet says that PCI 628X devices have a internal 16 bit DAC so technically the SNR should be atleast 90 db even if 6 db were removed for the harsh environment of the computer .
please advise , have anybody else faced this problem , the data sheet does not give a figure for the SNR ratio of the card , since i need to test a 12 bit adc , thought that 6289 would be up to the task since it has a 16 bit DAC.I am using the Noise shielding cables and also SCB-68 block , the block is far removed from other power supplies .
any ideas why the noise is occuring , one of my colleagues says maybe the harsh environment inside the pc enclosure causes it , is it necessary to use a separate PCI box for the card and then connect the card to the computer , is this standard procedure ?????.
and also does the PCI -6289 have a filtering option for the analog output , all i could find was the filtering for input.

Hi Tom
Thanks a lot for responding to the thread , did not expect a response in the holiday season . The SNR for the 12 bit one was a typo , was referring to the 16 bit onboard dac in the M series card , which technically should ensure a clean input signal having atleast 90 db .
The info you have given helps a lot , i suspect the conditions inside the pc might be causing it , also i am driving the analog output from the card at almost its limits of 2.5 MS/s , the sample rate specification for the card on the data sheet says 2.8 MS/s , also i notice the settling time requirement for the outputs is 3 us which i suspect will put the onboard DAC under quite a load.
If the conditions inside the PC cannot be rectified , where can i find a external PCI box which can be connected to the computer or does such a box exist only for the PXI cards ? will that necessarily rectify the problem and also since filtering is not possible on the card itself , I remember reading the scb -68 connector block has single RC output filter option , i would have to use discrete R,C components to make it but notice on the right hand corner some pcb holes are provided , would this help.
Would appreciate your Response
Thank you

I am using an NI PCI 6024 E board device for an analog output application. Can I generate two independent waveforms, one on each analog output channel?

I am using an NI PCI 6024 E board device for an analog output application. Can I generate two independent waveforms, one on each analog output channel? In attach I send a example of my vi to control one chanel, but i need to control both but with diferent waveforms.
Is the vi correctly programed to this propose?

Yes you should be able to do that. look at the signal generation examples shipped with LabView
You can create a 2 D array, with each row representing a wave form per channel. The number of points of the wave form (per row of the 2 D array) represent the number of points in the output buffer
The wave forms can have different amplitudes/shapes, and therefore they are independent in this sense.
However, you need to set the update rate,which is the same for both channels. The update rate together with number of points per buffer determines the frequency of the wave forms. This means the two wave forms will have the same frequency.
To have different frequencies, you need to have say, on wave form with one cycle per buffer, and the other waveform have 2 cycles
per buffer. in a case like that the frequency of the second channels is twice that of the first channel, and so on
The two wave forms are then not truly independent, they may have different amplitudtes/shapes, but related in frequency.

When using the analog inputs and analog outputs of the PCI-7344, what is the conversion between the voltage entering the card to counts? Similarly, what is the conversion between counts to voltage at the output of the card?

I am using the PCI-7344 to control my system. The analog inputs are connected to the output of my system while the analog outputs serve as feedback to the system. The system is a servo. I want to know what is the conversion between the voltage read at the input, to card counts, and finally to the voltage output to the system.

Carole,
If you are trying to do analog feedback with a servo motor, Chapter 14 of the manual talks about how to set up the torque feedback. Also linked below is a LabVIEW example of analog feedback.

How do I get an analog output signal from my PCI-MIO-16E-4 card?

I need an analog output from 0-10 V to control the mass range on a mass spectrometer. Do I use the DAC0out channel to do this? The manual only talks about analog out (ao) channels. Is this the same as DAC0out and DAC1out? How do I set up the DAQ assistant for this process? I do not need a waveform, only a constant signal.

Yes indeeded. The DAC0out and DAC1out are the analog output channels (ao0 and ao1).
Simply follow the examples that ship with LabVIEW. You can also easily create code with DAQ assistant.

Setting different analog output's parameters in PCI-6229 DAQ card

Hello,
We are using DAQ assistant to set the analog output parameters (frequency).
Is it possible to set different values for each channel using DAQ assistant?
If not using DAQ assistant, what is the other way to set it?
Thank You
Arunas

If you are trying to set different frequencies for waveform generation on two channels, the answer is No, it can't be done. If possible, you will have to pick a sample rate high enough to work for both signals, and use an over-sampled waveform.
Another choice would be to use a second device for the second waveform.

Synchronize two PCI Board for Analoge Output

Hi All
Has anyone a good example for synchronizing two MIO Boards over RTSI cable.
I found a lot examples to analoge input but nothing about analoge output.
Thanks

Hi Reto.
I posted to this once, but looks like it didn't make it. I checked the examples, and Ir eally didn't see anything that did what you wanted over the RTSI bus, so I made one. Check it out.

Synchronizing 1 PCI 6220 and 2 PXI 6711 Boards

Hello,
I have created a program that writes both digital signals to the PCI 6220 board and analog functions to two 6711 boards. Upon testing the output of these boards on the oscilloscope, I discovered that the timing of the digital board was about a half of a second behind the timing of the analog board. If anyone has any ideas about why this may be happeneing itd be greatly appreciated. I believe it is a synchronization mistake. I have the boards connected with an RTSI cable but i never reference the cable in the program.

One solution would be to run a wire (a real one! you know with copper inside it? ) from the counter output to one of the PFI lines on the same card and then tie the PFI line to RTSI bus...
There might be a more elegant way of doing it that someone could share, but this would certainly work. Just make sure that you document in your code the assumption that this jumper wire is in place.

How to avoid delay during analog output generation by changing its frequency?

Windows XP
LabVIEW 7.1
PCI-6036E + BNC-2120
Hi,
I am going to create a vi to generate an engine speed sensor signal (a simple square wave with specific missed pulses, in my case 58 pulses “teeth” and 2 missed pulses “missed teeth”) as an analog output but in addition give me the opportunity to control parameters for example frequency online to simulate the engine speed changes during running that vi. For this purpose I have started with “Continuous Generation.vi” which is available in NI Example Finder under the following path:
Hardware Input and Output > Traditional DAQ > Analog Output > Continuous Generation.vi
Then I modified it towards above mentioned goal, all related vi s are attached. The main vi is: "Motor Signal Generator_1.12.vi"
At the first try it looks that it works properly but when have a look on that more accurately with Oscilloscope (fortunately I have a good one: Agilent 54621A – 60 MHz, 200 Ms/s) obviously there is a gap (delay or Jitter) whenever I change the engine speed. It is also attached in Signal generation_problem report.doc file.
Note: Small gaps are OK and related to predefined missed teeth but the big one is happened during changing engine speed.
As far as I understand it is related to the time which case structure in AO C-GEN sub-vi needs for AO reconfiguration each time after changing the engine speed (update rate). How can I get rid of this delay or gap during signal generation and generating completely continuous signal?
I have to mention that obviously I changed the frequency by changing the update rate. The other possibility is to change the number of updates in one period (refer to "generate arb frequency.vi" in NI site: http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3E48F56A4E034080020E74861) which resulted in no delay however then I can not change the frequency continuously but step by step (for example jump from 5Khz to 2.5KHz immediately) and this can not pass to my application.
Any hint is appreciated.

NI-DAQmx VisualStudio C++ 6 Single point analog output

Specs: NI-DAQmx 7, VisualStudio C++ 6.0, PCI-6722,8channel AO
We have a very simple application: set a voltage (actually 6 channels) and keep it until we want it changed again, perform the change very quickly in response to an image capturing algorithm. So I don't need any waveforms or buffering.
In this forum post http://forums.ni.com/ni/board/message?board.id=231&message.id=3283&query.id=18094 you talk about an AOOnePoint example, but I get an error that the NI-DAQ driver does not support my device.
I may need to use NI-DAQmx, but how? I would like to use something like AO_VWrite(,,), maybe for 6 channels in one call. But I can't find it in NI-DAQmx. It seems I need to setup buffers and frequencies. I have a working sample, but it seems a slow and certainly overkill of this simple application:
// Link with \DAQmx ANSI C Dev\lib\msvc\NIDAQmx.lib
#include "NIDAQmx.h"
double[2] data;
int taskHandleAnalog;
int written;
void Init()
    DAQmxErrChk (DAQmxCreateTask("",&taskHandleAnalog));
    DAQmxErrChk (DAQmxCreateAOVoltageChan(taskHandleAnalog,"Device and Channel Info","",0,10,DAQmx_Val_Volts,NULL));
    DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandleAnalog,"",1000,DAQmx_Val_Rising,DAQmx_Val_ContSamps,NUMBER_OF_AO_SAAMPLES));
    DAQmxErrChk (DAQmxWriteAnalogF64(taskHandleAnalog,NUMBER_OF_AO_SAAMPLES,0,1.0,DAQmx_Val_GroupByChannel,data,&written,NULL));
    DAQmxErrChk (DAQmxStartTask(taskHandleAnalog));
void SetVoltage( double voltage )
    data[0] = voltage;
    data[1] = voltage;
    DAQmxStopTask(taskHandleAnalog);
    DAQmxErrChk (DAQmxWriteAnalogF64(taskHandleAnalog,NUMBER_OF_AO_SAAMPLES,true,10.0,DAQmx_Val_GroupByChannel,data,&written,NULL));

Hi,
It looks like you simply wants to output voltages on the analog output channels, but only wants one update at a time with no waveforms or buffering in DAQmx.
As I'm sure you know there are really just 3 types of measurements. Single Point, Finite, and Continuous. Since you want a single value at a time it's just a Single Point operation.
You can find DAQmx examples for single point operations in this path:
C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog Out\Generate Voltage\Volt Update
Simply place the DAQmx Write Code within a loop and you will be updating one value at a time, but multiple times when "we want it changed again".
